COACH-HINGE.

SPECIFICATION forming part of Letters Patent No. 729,407, dated May 26, 1903.

Application filed March 13,1903. Serial No. 147,575, (No model.)

To ctZZ whom, it may concern:

Be it known that I, FRANK P. PFLEGHAR, of New'Haven, in the county of New Haven and State of Con necticut, have inventeda new and useful Improvement in Coach-Hinges; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to bea full,'clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure 1, afront view of a hinge constructed in accordance with my invention, showing the hinge-plate in an open position; Fig. 2, a top or plan View with the hinge-plate in its closed position; Fig. 3, a rear view of the pillar-plate with the pintle-plate removed; Fig. a vertical sectional view of the same; Fig. 5, a perspective view of the pintle-plate removed.

This invention relates to an improvement in coach-hinges, and particularly to that class which are known as concealed hingesthat is, in which the pintle is set inward from-the faceplate-and is an improvement on the invention for which Letters Patent of the United States No. 244,293 were granted July 12, 1881, the object of theinvention being the construction of a hinge in which the pintle is rigidly supported and connected to the face-plate in a neat and attractive manner; and the invention consists in the construction as hereinafter described, and particularly recited in the claims. 7

Like my previous invention, I employ a plate A, adapted to be set flush with the pillar of a coach and secured therein by screws entering holes B in the plate. In the face of the plate is an oval opening C, and upon the back of the plate is a projection or housing D, extending inward at top and bottom beyond the opening C, so as to form a flange E at the top and bottom of the opening. C. In this housing is a substantially rectangular opening F, the outer edge of the housing projecting inward, forming a lipG, while the inner edge of the housing and plate is formed with an inclined surface H.

the curved arm J passes.

The hinge-plate I, which is secured to the door, is formed at the outer end of a curved arm J, the inner end K of which extends inward at an angle to the plate I, and this end K turns upon a pintle L, mounted'in the inner ends of parallel arms M, projecting inward from a pintle-plate N, which is formed with a clearance notch Q, through which The pintle-plate N fits the recess C in the pillar-plate A, to

which it is secured by screws 0 passing through the flanges E, which are formed with bossesP to give increased bearing for the screws, the face of the pintle-plate when in position being substantially flush with the outer face of the pillar-plate. The hingeplate moves in an arc of acircle, turning from the open position in Fig. 1 to the closed position in Fig. 2. The lip G aids in supporting the pintle-arms N, while the inclined surface H gives clearance of the movement of the curved arm. This construction gives a firm support for the moving member of the hinge,whichmay be readily removed and separated from the pillar-plate by the removal of the screws 0, which permits the pintle-plate to be withdrawn. This construction also permits of the convenient finishing of the parts, and the only opening through the pillar-plate is the clearancenotch in the pintle-plate, which is practically closed by the curved arm, thus preventing the possibility of the entrance of water into the pillar.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a coach-hinge, the combination with a-pillar-plate formed with an opening in its face, a housing on the back of said plate and projecting at the top and bottom into said opening, a pintle-plate having an opening in the pillar-plate and formed with inwardlyprojecting arms, and a hinge-plate having a curved and straight arm the inner end of the said arm mounted on a pintle supported by said pintle-arms, substantially as described.

2. In a coach-hinge, the combination with a pillar-plate having an opening in its face,

a pintle-plate adapted to close said opening In testimony whereof I have signed this and formed with inwardly-projecting arms, specification in the presence of two subscribno and a clearance-notch, a pintle mounted in ing witnesses.

the inner ends of the said arms and a hingeplate having a curved arm passing through FRANK PB LEGHAR' said notch in the pintle-plate, and a straight Witnesses:

arm mounted upon said pintle, substantially M. J. ROBERTS,

as described. I E. M. FOWLER.
